Sanitary component, namely jet regulator or jet former for flowing, fluid media, method of producing such a sanitary component and use of a sanitary component

ABSTRACT

The invention relates to a sanitary component, namely a stream regulator or stream former for flowing fluid media, consisting of property-defining components in a sandwich-like arrangement in the direction of flow which comprise at least one screen attachment, one diffuser plate assembly as well as a shell body having segments of stream-forming openings extending across its cross-sectional surface. The property-defining components are exchangeable and combinable so as to realize adaptability to different user and user requirements. A locking means is provided e.g. on the inner circumference of the shell body for this purpose as is a corresponding counter-locking means on the outer circumference of the diffuser plate assembly. The diffuser plate assembly exhibits, at least on its exterior, a flow rate class-specifying optical code and the shell body exhibits a stream type-specifying, namely laminar or aerated, optical code. The screen attachment is furthermore inserted into a circumferential inner recess of the e.g. circular diffuser plate assembly, preferably by means of a locking connection, whereby in the case of a flow regulator disposed between the screen attachment and the diffuser plate assembly, the screen attachment is of translucent or transparent design and the flow regulator exhibits another optical coding. In the case where no flow regulator is provided, the optical coding of the screen attachment is designed to match that of the diffuser plate assembly or be provided in a predefined combination.

The invention relates to a sanitary component, namely a stream regulatoror stream former for flowing fluid media, consisting ofproperty-defining components in a sandwich-like arrangement in thedirection of flow, a method of manufacturing such a sanitary component,as well as the use of such sanitary components, namely stream regulatorsor stream formers.

Stream regulators or stream formers marketed by the Neoperl GmbH companyunder the brand names “Neoperl®” and “Perlator®” have been part of theprior art for years.

At the same time, due to different standards, e.g. the European EN 246standard or the US ASME A112.18.1M standard, there needs to be a numberof different products available reflecting different flow rates ordifferent flow rate restrictions. Also, different stream patterns aresought such as, on the one hand, those mixed with air as so-calledbubbly flows and, on the other, laminar, crystal-clear flows of fluidmedia, while it is just as desirous to have control over the noiseemissions occurring in outflowing streams. The above requirementsfurther increase the number of different products which actually serveone and the same purpose.

The most essential components for stream regulators or stream formersfor flowing fluid media comprise means arranged in sandwich-like mannerin the direction of flow; i.e., customarily a circular screenattachment, a circular diffuser plate assembly as well as asubstantially cylindrical shell body having segments with stream-formingopenings extending across its cross-sectional surface which can beconfigured in one piece with the shell and/or as insert plates.

The screen attachments or filter screens, stream regulators, flow rateregulators, flow restrictors and/or check valves upstream the directionof flow protect the sanitary insert elements from dirt particles carriedalong in the water. The screen attachments are usually connected to theother structural components and are inserted as one associatedfunctional unit in an outflow nozzle attached to the water outlet of afaucet with e.g. screws or are inserted directly into the faucet. Screenattachments are typically made from a nontransparent synthetic materialwhich obstructs the view of the insert elements disposed at the outflowside. As such, the user thus cannot readily tell which additionalstream-forming or flow rate restricting means are provided inside thestream regulator.

Since, as noted above, the spectrum of stream regulator or stream formervariants span different flow rate classes, whereby only 6 l/min at 3 baris required to operate a hand washbasin faucet, for example, while 30l/min at 3 bar is recommended for filling a bathtub, and as also notedabove, there are different technologies for producing the flow rateclasses as well as producing laminar, crystal-clear or aerated streams,the user of commercially-available stream regulators, especially whendealing with spare parts, is often not able to tell which streamregulator needs to be inserted into the existing faucet so that it willoperate trouble-free and comply with the necessary comfort and safetyrequirements.

Moreover, since even for a large multitude of final products, the numberof function-defining components should be kept as low as possible fortechnical manufacturing and cost-cutting reasons, and ultimately to alsokeep stock to a minimum, attempts have already been made to provide theentire necessary array of products using a combination of just a fewcomponents or component units. However, a manufacturing process also hasto ensure, subject to quality assurance, that only those components arein fact used which, as a whole, ensure the desired parameters of thestream regulator the customer will ultimately use.

A further difficulty in the prior art with regard to identifyingsuitable stream regulators relates to the fact that due to faucetsnormally being standardized, it is not possible to realize type-relevantor application-specific measures with e.g. a particular external design.This is compounded by the fact that stream regulators are frequentlysold as OEM products, whereby there are only specifications from theparticular faucet manufacturer, both with respect to the streamregulator itself as well as the typically metallic outer housing whichaccommodates the stream regulator in its interior and which is connectedto the outlet faucet, not, however, specifications on the specificproperties of the particular stream regulator. In other words, there isa relatively high risk of confusion relative the prior art, particularlywhen the products are sold without an outer housing for spare partneeds.

Based on the above, the task the invention therefore addresses is thatof further developing a sanitary component, namely a stream regulator ora stream former for flowing fluid media, which can be clearly identifiedboth in the manufacturing process as well as in subsequent use byvarious different design and technological measures and whereby it ispossible to realize the manufacture of such components in an effective,cost-efficient and simple manner without compromising the qualitystandards respective the final product.

A further task of the invention is the developing of a method formanufacturing such sanitary components, namely stream regulators orstream formers, which is conducive to an automated assembly of streamregulators or stream formers.

Last but not least, it should be possible to use such sanitarycomponents, namely stream regulators or stream formers, in such a mannerthat use of unsuitable components can be excluded with a probabilitybordering on certainty, e.g. a flow rate class for filling a bathtubused with a faucet for a hand washbasin. The same applies to the case,as should be avoided, of OEM customers using unsuitable components.

The solution to this task of the invention is realized with a sanitarycomponent in accordance with the features of claim 1, a method formanufacturing such a sanitary component in accordance with thedefinition of claim 20, as well as the specific use of sanitarycomponents according to the teaching of claim 22, whereby the subclaimsconstitute no less than functional designs and embodiments.

The sanitary component according to the invention, namely in the form ofa stream regulator or stream former for flowing fluid media, consists ofproperty-defining components in a sandwich-like or stacked arrangement.

These components comprise at least one preferably circular screenattachment or filter screen, one preferably circular orcircular-cylindrical diffuser plate assembly as well as a preferablycylindrical shell body having segments with stream-straightening orstream-forming openings extending across its cross-sectional surface.

To realize an adaptability to the most diverse user and userequirements, said property-defining components are exchangeable andcombinable. To this end, locking means are for example arranged on theinner circumference of the shell body and corresponding counter-lockingmeans are arranged for example on the outer circumference of thecircular diffuser plate assembly. These means are preferably formedintegrally; i.e. as one piece with the respective component.

The preferably circular or circular-cylindrical diffuser plate assemblyexhibits a coding specifying the flow rate class, at least on itsexterior, and the shell body exhibits a coding defining the flow type orthe stream pattern respectively. The flow type or stream pattern ispreferably laminar with a crystal-clear stream or bubbly; i.e. aerated.The flow type or stream pattern is symbolized by a specifying opticalcoding.

In a further embodiment of the inventive stream regulator, the outflowarea of the shell body comprises a pivotable insert or pivotable streamstraightener provided with stream-forming means.

With the circular embodiment of the diffuser plate assembly and theshell body, the inside of the shell body is configured in the shape of aspherical cap and the pivotable stream straightener likewise has acomplementary spherical cap shape. The pivotable stream straightenerallows the outflow stream to be titled or swiveled at a specific anglefrom the longitudinal axis of the stream regulator. Moving thestraightener in terms of the desired pivoting can be realized withoutany auxiliary means; i.e. by simply pressing a finger lightly on theunderside of the plate.

The type of given stream regulator design, with or without a pivotablestream by means of a movable stream straightener, can be symbolized by afurther optical coding.

In a modified embodiment of an inventive stream regulator, a coating ofa defined minimum thickness or minimum strength made of an elastomermaterial, e.g. silicone, is provided on the outer surface of the flowstraightener, which can also be formed integrally with the shell body.This coating thereby follows the contour or structure of thestraightener in the direction of flow. The especially calciferousdeposits which adhere to the elastomer coating over the serviceable lifeof the stream regulator can be removed very easily by gently moving;i.e. rubbing the coating.

The type of coating on the exterior of the flow straightener moreoverallows another haptic; i.e. tactile coding in the sense of the inventivetask.

Finally, stream regulators are known which are not accommodated within ametallic outer sleeve but rather screwed directly into the e.g. tubularend of an outflow faucet. Such concealed stream regulators comprise ashell body with a male thread and a washer which is usually disposed ina circumferential groove. Said washer can have an optical; i.e. colorcoding differing from the color coding of the shell body. This codingthen symbolizes e.g. the type of male thread, the thread pitch or thelike.

In one embodiment, the screen attachment is inserted into acircumferential inner recess of the circular diffuser plate assembly,preferably by means of a locking or snap-in connection, whereby in thecase of a flow regulator disposed between the screen attachment and thediffuser plate assembly, the screen attachment is designed to betranslucent or transparent and the flow regulator has another opticalcoding.

In the case where no flow regulator is provided, the optical coding ofthe screen attachment is designed to match that of the diffuser plateassembly or be provided in a predefined combination.

In a particularly preferred embodiment of the teaching of the invention,the optical codings are designed as respectively different colorcodings.

The color gradings or color differences to the respective codings relateto color temperatures which can be detected by means of optoelectronicimage detection and analysis. It is also within the sense of theinvention for the color gradings to be readily perceived by the humaneye.

The color codes for the screen attachment comprise 21 colors, namelydark green, burgundy, light green, light blue, yellow, dark blue, darkgray, light gray, gray, orange, blue, ivory, green, brown, olive, red,beige, black, pink, purple and white.

The color codes for the flow regulator comprise ten colors, preferablynamely light green, dark gray, green, purple, dark blue, pink, orange,black, yellow and white.

The color codes for the diffuser plate assembly comprise at least elevencolors, namely dark green, burgundy, light green, light blue, yellow,dark blue, dark gray, light gray, gray, orange and neutral. The neutralshade is to be understood as a color ensuing from the preferablysynthetic material used, along with its material properties, without theaddition of any color. When using the preferable POM material, thisresults in a shade which is opaque to milky white.

The diffuser plate assembly is typically inserted into the shell body,but can also be configured as, for example, a component having anannular outer contour differing from the color of the shell body. Aneutral color to the diffuser plate assembly then symbolizes anon-noise-reducing model while a colored variant symbolizes anoise-reducing model.

The color coding to the shell body comprises at least two colors,whereby a first color is associated with a shell body having air supplyslots and a second color is associated with a shell body without airsupply slots.

The first color is preferably dark gray while the second color ispreferably light gray, whereby each shell body is of a solid-coloredsynthetic material.

A complementary color code for the shell body or the base of the shellbody, namely with a colored marking clearly differing from theafore-mentioned two colors, applies to an embodiment in which the flowstraightener is configured as a pivotable insert for the shell body. Forexample, the color white symbolizes a pivotable embodiment while thedark gray or light gray colors symbolize a fixed embodiment.

The flow regulator used in the respective sanitary component comprises acontrol gap, the flow cross-section of which can be altered by means ofan elastically deformable ring under the pressure of the flowing fluidmedium.

The transparency to the screen attachment is selected such that theposition of the deformable ring is or remains identifiable on the onehand and, on the other, the entire flow regulator including its codingis visible.

In one embodiment of the invention, the elastic ring can likewiseexhibit a visually identifiable coding, in particular a color coding,which differs from the control gap or its surrounding area.

The screen attachment is configured to have a convex or conical shape atthe inflow side.

The screen attachment preferably exhibits polygonal screen openings andhas an annular collar which locks into place in the inner recess of thecircular diffuser plate assembly. The basic tint to the screenattachment can moreover provide a simple, easily-grasped indication ofthe preferred specific application, e.g. “water-saving,” maximum flow,”or “normal use.”

As set forth above, subject to the use-specific requirements, aselection can be made from among different diffuser plate assemblies andshell bodies, as well as flow regulators where applicable, whereby thesecomponents can be easily assembled using for example locking means orsnap-in connections. Although there are only a small number ofindividual components visible in the assembled state, this proposed typeof optical coding provides the opportunity to make a visualdetermination just by a quick identification of the correspondingmatching pattern or colored depiction; i.e. without any other aid, as towhether the given product will correspond to the expected requirementsand/or whether it will be suitable for its intended use.

With respect to the method of manufacturing a sanitary component, namelya stream regulator or stream former for flowing fluid media, thesandwich-like arrangement of the property-defining components in thedirection of flow is again in turn assumed, whereby same includes atleast one e.g. circular screen attachment, one e.g. circular diffuserplate assembly as well as an e.g. cylindrical shell body having segmentsof stream-forming, stream-straightening openings extending across itscross-sectional surface.

These property-defining components are exchangeable and combinable so asto realize adaptability to different user and use requirements. To thisend, specific locking means or connections which are integrally formedon or inserted into the corresponding components are preferablyemployed.

The e.g. circular diffuser plate assembly exhibits an optical codingspecifying its flow rate class, at least on its exterior, and the shellbody exhibits an optical coding specifying flow type; i.e. laminar oraerated.

The screen attachment can be inserted into the diffuser plate assembly,preferably by means of the afore-mentioned locking connection, wherebyin the case of a flow regulator inserted between the screen attachmentand the diffuser plate assembly, the screen attachment is of atranslucent or transparent configuration.

The flow regulator likewise exhibits a specifying optical coding. Whenno flow regulator is provided, the optical coding to the screenattachment matches that of the diffuser plate assembly or is provided ina predefined combination, particularly color combination.

Based on customer-specific requirements as to the flow rate class andrespective stream pattern and/or flow rate desired, the method's codingof the property-defining components is gleaned from a code table tomatch or approximate the customer-specific requirements to the greatestextent possible.

This information facilitates the retrieval of the components frominventory as well as their assembly, and also allows for automating andcontrol. Optoelectronic image acquisition and digital image processingmethods are particularly well-suited for such control purposes.

The use or application of sanitary components pursuant the invention, inparticular as defined in claim 1, is realized drawing on amanufacturer-authorized code table which indicates which specificoptical coding as identifiable on the components without disassemblycorresponds to, or approximates to the greatest extent possible, therespective application in terms of stream pattern, flow rate restrictionand/or flow rate class.

It is noted at this point that realizing the teaching according to theinvention not only can optimize the manufacturing process and improvequality assurance, but also allows the end user to readily identify therespective replacement model, ultimately with the consequence ofsimplifying the preparing of orders and the actual purchase.

The following will draw on the example of an embodiment as well as referto figures and tables in specifying the invention in greater detail.

In accordance with FIGS. 2 and 2 a, the sanitary component comprises aflow-regulated stream regulator (FIG. 2 a) having property-definingcomponents arranged in sandwich-like manner in the direction of flow.FIGS. 1 and 1 a show a sanitary component having a stream regulatorwhich only forms or straightens the stream.

The most essential element of the sanitary components according to theinvention is the shell body 1 provided with flow-straightening,stream-forming means 2 (flow straightener) comprising openings at itsunderside or lower section.

The shell body 1 has slot-like openings 3 across certain sections of itsouter circumference which serve in the supply of ambient air; namelywhen an aerated, bubbly stream pattern is to be produced.

A circular diffuser plate assembly 4 is disposed upside the shell body 1in the inflow direction. This diffuser plate assembly 4 exhibits aplurality of special, flow-dividing openings of different cross-sectionsor varying longitudinal cuts so as to accelerate the inflowing fluid andpass it through to the flow straightener 2 arranged downstream in thedirection of flow.

The diffuser plate assembly 4 is brought into contact with the interiorof the shell body 1, e.g. by means of a locking connection 5, and isfixed accordingly.

Thus, to realize an adaptability to different user and use requirements,the property-defining components, namely the diffuser plate assembly 4and the shell body 1, are exchangeable and combinable with thestream-forming means 2. To this end, locking means are disposed,preferably integrated, on the inner circumference of the shell body 1,while the corresponding counter-locking means are arranged, preferablyintegrated, on the outer circumference of the circular diffuser plateassembly 4.

The circular diffuser plate assembly 4 is coded at least on its outerside. The shell body 1 is likewise coded at least on its outer side,whereby both the circular diffuser plate assembly 4 as well as the shellbody 1 are preferably made of a solid-colored synthetic material,whereby the synthetic material's color corresponds to the desiredoptical coding.

A screen attachment 6 is also inserted into the diffuser plate assembly4, preferably by means of a locking connection 5.1 or by flush-fitting.For this purpose, one embodiment provides for the circular diffuserplate assembly 4 to comprise an inner recess and the screen attachment 6a partial or full collar complementary thereto.

In the case of a flow regulator 7 inserted between the screen attachment6 and the diffuser plate assembly 4 (see FIGS. 2 and 2 a), the screenattachment 6 is of a transparent design pursuant this embodiment (seeFIG. 2) and the flow regulator 7 has another optical coding whichdiffers from that of the given diffuser plate assembly 4.

In the case of there being no flow regulator 7 (FIGS. 1 and 1 a), theoptical coding of the screen attachment 6 is designed to match that ofthe diffuser plate assembly 4 or is provided in a predefinedcombination, in particular a color combination in accordance with Table1.

A consideration of Tables 1 to 3 and the embodiment of the sanitarycomponents according to FIGS. 1 a, 2 a and 3 allows for readily derivingboth the scope of application as well as the product specification orparameters.

The product pursuant FIG. 1 or 1 a is accordingly a stream regulatorhaving a shell body 1 and slot-shaped openings 3 which, pursuant Table3, is of a dark gray color. A dark gray shell body 1 here signifies thatthe product produces an aerated stream.

The combination of dark blue diffuser plate assembly 4 and dark bluescreen attachment 6 results in a stream regulator suitable for flow rateclass B (see Table 1).

The sanitary component according to FIGS. 2 and 2 a relates to aflow-regulated stream regulator, namely for the reason that its screenattachment 6 is transparent. The flow regulator 7 visible throughtransparent screen 6 is yellow, meaning a flow rate of a maximum 8.3l/min at its intended use and pursuant the impending, also variable,pressure.

The elastically deformable ring 10 disposed in a control gap 11 is alsovisible. In the unloaded state, this ring 10 cannot be deformed and mustassume a target position with respect to the flow cross-section to bealtered. The corresponding position of the deformable ring 10 can bereadily deduced with the transparent screen attachment 6 as employed.

With reference to FIG. 2 a and a consideration of Table 3, the shellbody 1 shown therein likewise has a dark gray color, signifying that thestream produced in this case is also aerated.

Should the shell body 1 have a light gray color, that would signify thata laminar stream would be produced in accordance with the intended useof the respective stream regulator.

The sanitary component of FIG. 3 with its multi-member diffuser plateassembly comprises a screen 12 with a through-flow opening 13. Thisthrough-flow opening, the flow rate class-defining dimension of which isnot readily visible to the user, can be symbolized by the coloring tothe ring member 14 and/or the coloring to the screen attachment 6. Thering member 14 can be configured as an integral part of the diffuserplate assembly.

The embodiment of the stream regulator according to FIG. 4 hasessentially the same basic construction as that shown in FIGS. 1 and 2,respectively 1 a and 2 a.

The diffuser plate assembly is disposed in the interior of shell body 1and has an upper part 4.1 for the purpose of accelerating the stream anda lower part 4.2 for dividing and decelerating the accelerated stream.The flow straightener 2 is disposed underneath the diffuser plateassembly as pivotable element 8. In order to obtain the pivoting motionshown as an example in FIG. 4, the lower section of the innercircumference of shell body 1 is configured in spherical cap shape. Theouter circumference of pivotable element 8 has the correspondinglycomplementary spherical cap shape 9. Because it is possible to pivotelement 8, the outflowing stream can be moved back and forth at aspecific angle, yielding substantial applicational advantages for awater faucet fitted with same.

The color coding of the pivotable element 8 as the base of the shellbody can be designed to differ in color from the shell body 1 so as tolikewise enable a clear correlation in the sense of the invention, e.g.the color according to Table 8.

Providing an additional haptic coding to the outer surface of the flowstraightener or the shell base allows for the defining of the sanitarycomponents' resistance to lime deposits pursuant Table 7. The choice ofcolor to the non-transparent screen attachment moreover offers the userof the sanitary component a clear indication of its preferred use, e.g.conserving water. For example, according to the present Tables 4 and 5,the color “green” signifies water economizing based on a reduced flowrate.

It is to be noted at this point that all the afore-mentioned opticalcodings are predefined irrespective of the given diameters or dimensionsto the sanitary components. The optical codings relate only to thestream regulator's function-defining or comfort-defining properties.

FIG. 5 shows a sanitary component, the shell body 1 of which comprises amale thread 15 so that it can be screwed directly into a complementaryfemale thread of an outflow faucet. The codings as described above canalso be used here as well for flow rate classes and/or flow regulation.There is also the additional possibility of defining the type and/orpitch to the male thread 15 by the color code of the requisite washer16.
